Endoscopic ultrasound in early gastric cancer: Diagnostic accuracy and Tis/T1a lesion over staging risks

Key Points

• Diagnostic accuracy of endoscopic ultrasound is notably decreased for Tis/T1a early gastric cancer when gastric ulcers are present.
• Findings indicate that staging should be approached with caution when dealing with ulcer-related lesions.
• Endoscopic ultrasound is used for cancer staging, but its effectiveness varies with the presence of ulcers.
• Caution in EUS interpretation is emphasized for accurate clinical decision-making regarding treatment options.
